Trends can consume very large quantities of memory. Older versions of 800xA have known memory leakages in the trend function. Check with your regional ABB support center if any rollup, etc is available.

Workplace process drives all monitors simultaneously and with shared system resources. The content on one "large" monitor may affect other monitors.

If problems arrive with increasing number of trends or with amount of time trends have been on screen we probably have a memory issue.

1. Use 64-bit operating system to allow workplace to use more than 2 GB RAM

5. Consider using separate workplace process (=2 workplaces running in same computer) for 3rd monitor. Workplace layout can be set to have "trend workplace" to arrive on monitor three automatically. No additional license required (one computer can only drain one workplace license).

800xA 5.1 FP4 RevE used and 64Bit Windows I Think the memory no problem I already try to separate workplace the trend display and then same . I just change the graphic card 2GB from 512MB look like the 2GB graphic card is slow. I received support line mail he is the more then 72 variable used then slow the system.. is it right?

Measure Virtual Bytes as mentioned. What does the memory trend look like as you add more curves?

With separate workplace, did "operator" WP become affected by the "trend" WP when enough trends are opened/added?

If WP trend disturb WP operator it sounds like a drawing performance issue? We used to have redraw problems in the past, especially with the PG2 embedded mini trend. Some configurations led to excessive "paint pixel" operations which could saturate a graphic card and especially non-HW-accelerated configs (RDP, Matrox Extio, etc).

I recommend asking your regional support center to forward a support case to our SE L3 center in Västerås where we could engage R&D specialists, etc.

Normally use the 3 screen workplace upper screen shot is normal workplace, but this workplace navigation button click and then not working, more then 72 variable trend display, do not change the any action. should be close the trend display less then 71 variable and then navigation button click and graphic display change working.

Also keep an eye on CPU usage. Trend options like Auto Scroll can affect CPU. Experiment with trend settings (scroll, treatment, log name, etc). A workplace shall normally not exceed 25-50% CPU time.
Make sure you know how CPU time is presented, eg regular task manager may report 12% for a process on an eight core machine (eg Intel i7) but if only one thread is involved it is same as 100% for that thread and problems may occur if it wasn't designed to draw full load on one thread only.
